CR-410C Coffee colorimeter
The CR-410C handheld coffee colorimeter is specifically designed to measure the color of whole green beans, roasted beans, and roasted coffee using industry standard measurements.
The CR-410C coffee colorimeter easily and accurately measures the color of coffee in a variety of forms: whole green beans, roasted beans, and roasted coffee.
Without a colorimeter, coffee bean color measurement is conducted either visually or with bulky, expensive instruments. The CR-410C is a low-cost, portable option that uses the SCAA specialty coffee index to calculate the color, difference from a standard, roasted level (light, medium, medium dark, dark), and pass/fail information. It also includes features our Food Color Indexing Technology (FCIT).
Features the ability to measure whole bean, powder, instant, and lyophilized coffee forms. This instrument is easy-to-use and has lower cost of ownership compared to competitive models.
- Easy-to-use – the CR-410C calculates measurements with the push of one button and can supply all the information needed in one printout
- Portable – handheld unit makes measuring effortless
- Industry standard – measurements are calculated based on the coffee industry standard established by the Specialty Coffee Association of America (SCAA)
- Ability to measure multiple forms – can measure whole coffee beans, powder, instant, and lyophilized forms
- Affordable – considerably more affordable than competitive models

Case Studies:
Food Industry Color Control
In today's retail world of behind glass, chilled, frozen, boxed, dried,
vacuum-packed and plastic wrapped foods, eye-appeal is far more
important than nose-appeal.
Both fresh and processed food producers know this well, and are
increasingly adopting instrumental color measurement technologies
and practices to control color better across a wide range of applications.
Clemson University: Understanding and Controlling Color
With the increasing diversity of products, product recognition is becoming more important. Along with product design, color is one of the major factors in creating a product image. It has a great effect on market appeal and sales.
The average consumer will not accept the color ranges that were the industry standard ten years ago. They are always searching for a better product - one that gives them the desired properties with a minimum of variation. Because of these requirements, companies are becoming increasingly concerned about color.
